Step 10: long term monitoring (LTM) (if required)

The objective of Step 10 is to implement a long-term monitoring (LTM) strategy at sites where the remediation/risk management (R/RM) objectives have been met but where conditions are such that the site could not be closed. For example, a risk management site would likely require long term monitoring. Long-term monitoring (LTM) may not be required at all sites. According to the 10-step Approach, LTM is meant to confirm that the nature and extent of the remediation activities have been carried out as per the site management goals, and that the objectives of the remediation or risk management strategy continue to be met over time to protect human health and the environment. Sustainable methods for site monitoring and contracting should be implemented as part of the LTM. Climate change effects should be considered during the development and assessment of the monitoring program in order to take potential changes in site conditions and exposure pathways into account. Stakeholders should be consulted as appropriate.

LTM objectives must be achieved and verified before a site can be closed, indicating that no further action is required. However, at some sites, perpetual monitoring may be required.

Once the LTM Strategy has been completed satisfactorily and the site can be closed, a closure tool should be completed, or updated. For FCSAP funded sites (R/RM activities) the Site Closure Tool (SCT) (FCSAP, 2012) must be completed and submitted to the FCSAP Secretariat.

If LTM objectives have not been met (e.g. monitoring results indicate exceedance of objectives), the exceedances should be reported to the appropriate level of management and custodians should re-evaluate the LTM Strategy and/or the Remedial Action Plan (RAP)/Risk Management Plan (RMP) (see Step 7).

Step 10: Long-term Monitoring (if required)
Long description

All activities in Step 10 should consider the future impacts of climate change on the site and should aim to use sustainable approaches. Review Remediation/Risk Management (R/RM) implementation activities and findings from previous steps. Update long-term monitoring objectives and the monitoring plan; implement the monitoring plan and compare results to monitoring objectives. If long-term monitoring objectives are not obtained, report Exceedances and reevaluate LTM strategy and/or RAP/RMP. Return to previous steps, as appropriate, to implement corrective action. When long-term monitoring objectives have been obtained, complete the SCT and TRAV if applicable. Then no further action is needed. Close the site on the FCSI and record the rationale.
